Hacking Cryptography, Video Edition

In Video Editions the narrator reads the book while the content, figures, code listings, diagrams, and text appear on the screen. Like an audiobook that you can also watch as a video.

Learn how the good guys implement cryptography and how the bad guys exploit it.

Everything we do in the digital world is protected by cryptography. But when pure math and algorithms are implemented in code, vulnerabilities emerge and can be exploited by hackers and bad actors. Hacking Cryptography details dozens of practical cryptographic implementations and then breaks down the flaws that adversaries use to exploit them.

In Hacking Cryptography you’ll find unique guidance for understanding how cryptography has failed time and again, including

DUAL_EC_DRBG random number generation using backdoored constants
Exploiting the RC4 stream cipher, as used in WEP
Block ciphers for padding oracle attacks and manipulation of initialization-vectors
Exploiting hash functions by using length extension and rainbow table attacks
Implementing RSA key generation vulnerable to short private exponents and exploiting it using the Weiner attack
Exploiting PKCS1.5 padding by using Bleichenbacher's signature-forgery attack

In Hacking Cryptography you’ll learn the common attack principles used against cryptographic security, and how to spot the implementation errors that make cryptography unsecure. Throughout, you’ll explore historical examples where popular cryptography has failed, such as the root key compromise for Sony PlayStation 3, and see what impact those failures have had on modern cryptography.

About the Technology
Even the strongest cryptographic systems in code and hardware leave cracks and vulnerabilities a would-be attacker can exploit. In this book, you’ll learn to write cryptographically secure code, sidestep common pitfalls, and assess new bugs and vulnerabilities as they are discovered.

About the Book
Hacking Cryptography helps you secure your systems by revealing the “lockpicks” bad actors use to break cryptographic security. It dives deep into each exploit, explaining complex concepts through real-world analogies, annotated examples, and pseudo-code—no advanced mathematical knowledge required. As you read, authors Kamran Khan and Bill Cox demystify opaque cryptography concepts and techniques so you’ll understand the “why” behind each best practice.
